Title: Ic pellet
Inventor: NISHIAKI EIJI
IPC: H01L21/02
Filed: 1987-04-20
Abstract: PURPOSE:To avoid the break of a pellet at the time of manufacture and improve the yield and the reliability of product by chamfering the corner of the pellet. CONSTITUTION:A pellet 1 wherein the corner 3 is out is obtained by making a V-shape scribing groove 2 at the time of wafer dicing and by rupturing. After the die bonding of the pellet, the bonding pad of the pellet and the electrode of a container are connected with a wire 4. This avoids the break of the pellet because the collision of the collet of a mounter with the corner of the pellet at the time of the die bonding is prevented. Then, at the time of wire bonding, the yield of a product is improved because the interval between the wire and the pellet is made greater and the contact of the wire with corner of the pellet is prevented. Furthermore, a voil or a pin hole is reduced by improving the flow of a resin at the time of transfer molding.

Title: Thermo-sensible flow detector
Inventor: SATOU HIROSHI
IPC: G01F1/69
Filed: 1982-06-07
Abstract: PURPOSE:To achieve a smaller size, less weight and a higher response to a detector by arranging a means of increasing the flow velocity of a fluid on the upstream side of a heat generating body so that the fluid creates a stable turbulence with reduction in the sectional area of a piping. CONSTITUTION:An insulation oil 6 flows into a nipple 5 through a hose 10. This flow is reduced greatly with a nozzle 9 and crosses a heat generating body 1 made up of a tungsten wire as jet current. At this points, the flow is stable creating a turbulent area with a Reynolds number exceeding 3,000 in terms of the min. measuring flow rate. Under such a turbulent condition, the power fed to the heat generating body 1 is detected with a detection circuit 7 to find the flow velocity of a fluid 6 whereby a flow rate proportional thereto is obtained. This enables the measurement in a stable turbulent condition thereby reducing the size and weight with a shortened pipe. The tungsten wire forming the heat generating body 1 increases the resistance value with a rise in the temperature to improve the response of the detector.
